BALL-COCK.

Specification of Letters Patent.

Patented Dec. 28, 1915.

Application filed. July 3, 1914.. Serial No. 848,710.

To all whom it may concern Be it known that I, JOHN SHANKs, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Barrhead, Renfrewshire, Scotland, have invented a certain new and useful Improvement in Ball-Cocks, of which the following is a s ecification. I

TlllS invention relates to improvements in ball cooks for controlling the supply of water to cisterns or the like of the ty e wherein the valve proper is carried by a iaphragm, and has-for its primary object to rovide a fitting which insures silence of delivery following discharge irrespective of the wa r pressure.

The invention is illustrated in the accompanying drawing in which Figure l is a vertical section of a construction embodying the invention; Fig. 2 illustrates a form of deflector different from that shown in Fig. 1.

The same reference letters denote similar parts in the several views.

Referring to the drawing, 1 denotes the diaphragm which is so fitted in relation to the water inlet connection 2 that the water inlet to the diaphragm casing 3 is eccentric to the diaphragm 1, the valve part 4 being disposed centrally of the diaphragm l. The diaphragm and the valve part 4 form a diaphragm valve which cooperates with a seating presented by the end face of an outlet connection 5 from which connection the water passing the diaphragm valve flows into the cistern or into a silencing tube 6 i (Fig. 2) and thence into the cistern. Preferably fitted at the outlet of said connection 5, or at-the flan ed end of said silencing tube 6, is an adjusta le ported tubular member 7 the ports 7" ofwhich may be more or less covered according to the position of said member. For example, said member 7 may be screw-threaded into the end of said conmotion 5 or silencing tube 6' and according to the position to which it is adjusted byrotation of a wing 8 formed on a disk 8" on the end thereof, the ports may be more or less covered; the extent to which the ports are covered being varied to suit the pressure. The said disk 8 is so positioned in relation to the end face 9 or flanged end of the outlet connection or silencing tube that the water is deflected from a truly vertical path and passes into the cistern in the form of a thin film. The flanged part 9}, attached to the lower end of the outlet connection or s lenclng tube 6 incloses the disk-like portlon or member which extendsradially beyond the ported part of the adjustable deflector, so that said part 9 serves as a hood to inclose the said disk-like portion 7 of said ad ustable deflector, and thus acts to direct the discharging water downward. Alternatively, any suitable form of deflector may be em loyed.

y-water passes to the side of the diaphragm 1 remote from the inlet by way of a perforation presented by an eyelet 9, and to insure that such perforation shall not be choked by rit, etc, the eyelet is entered by a needle-l1 e projection 10 formed on or fixed to the casing 3 on either side of the diaphragm, said projection 10 serving on fluctuation of the diaphragm to dislodge any obstruction tending to choke the perfora- As shown, in Figs. 1 and 2, there is fitted Y to the outletconnection an after-service tube. 14 for refilling the closet pan after dis-' charge. To prevent the possibility of undue waste of water, the said after-service tube 14 is preferably fitted with a manually adjustab e cook 15 controlling the flow of water through said tube 14.

As shown in Flg. 2, a release tube 16 may i be fitted to the'diaphragm casing, said release tube serving to conduct excess water from the side of the diaphragm adjacent to the member 12.

The'ball cock may be fitted so that the diaphragm is-located in a horizontal plane or a vertical plane or any intermediate plane.

The pressure of the water in the chamber of the valve through theinlet connection 2 on the diaphragm 1 is equal, per unit area, owing to the by-water communication to the lower surface of said diaphragm permitted by the port 9 in said diaphragm. As the upper surface of the diaphraim valve is of reater effective area than t e lower surace thereof the water pressure in the valve chamber will normally hold the said valve in engagement with its seat on the outlet connection?) through which water is discharged into the cistern, to fill the same. The release valve 12, which in the construction herein shown has a sliding fit on the nipple through which the port 11 is formed, will, when the cistern tank is v filled with water, be held to its seat by an elbow or projection on the float-controlled lever 13.

When, however, water is discharged from the cistern, for-the flushing operation, and the float-controlled lever 13 falls so that it nolonger holds the release valve 12 to its a in the valve chamber so as to close the diaphragm valve and to shut off the flow of water to the cistern.

I claim 1. In a ball cock cistern water-supply valve, in combination, a valve casing having an eccentric inlet and a central outlet connection, a release valve on said casing, a float-controlled member for operating said release valve, a movable diaphragm valve located in said casing and controlling said outlet connection, a freely movable part of the diaphragm portion of said valve having an eccentric perforation for passage of b water, and a fixed member penetrating sa1d perforation and serving to remove obstructions tending to choke said perforation.

' 2. In a water supply valve, the combination with a valve casing provided with an outlet connection to the cistern, of an adjustable deflector located at the discharge end of said outlet connection and consisting of a member comprising a ported tubular part having an adjustable connection with the discharge end of said outlet connection, so as to vary the exposed area of the ports thereof, and a disk-like portion closing one end of said ported tubular part and extending radially beyond the ported portion thereof, said ports being between said disklike portion and the end wall of said outlet connection so as to discharge water into the cistern in the form of a thin film.

3. In a Water supply valve, the combination with a .valve casing provided with an outlet connection to the cistern, of an adjustable deflector located at the discharge end of said outlet connection and consisting of a member comprising a ported tubular part having an adjustable connection with the discharge end of said outlet 'connection, so as to vary the exposed area of the ports thereof, and a disk-like portion closing one end of said ported tubular part and extending radially beyond the ported portion thereof, said ports being between said disk-like portion and the end wall of said outlet connection so as to discharge water into the cistern in the form of a thin film, and a hood on said outlet connection inclosing the said adjustable deflector.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN SHANKS.
